Sort Method
The Sort method sorts the ValueList of the ListviewField based on the content of one of its columns.
This method has the following syntax:
integer = ListViewField.Sort(colindex = integer[, direction = integer]
          [, casesensitive = integer][, updchoicelist = integer]
          [, coldatatypecode = smallint][, emptyvaluecomparison = smallint])
This method has the following parameters:
colindex
Specifies the index of the column to be sorted on. Its value must be between 1 and ColAttributes.LastRow.
direction
Determines the sort direction. Must be either AS_ASC or AS_DESC.
Default: AS_ASC
casesensitive
Determines whether the Sort method sorts strings with case sensitivity. Must be either TRUE or FALSE.
Default: FALSE
updchoicelist
Determines whether the display should be refreshed to reflect changes in the value list. Must be either TRUE or FALSE.
Default: TRUE
coldatatypecode
Specifies the code of the datatype to be used for sorting the column. Valid values are:
DTC_VARCHAR
DTC_INTEGER
DTC_FLOAT
DTC_DATE
DTC_MONEY
Default: DTC_VARCHAR
Descriptions of system constant values and their numeric equivalents are listed in DatatypeCode Settings.
emptyvaluecomparison
Specifies how empty values are compared with non-empty values. Valid values are:
EVC_LT
EVC_GT
EVC_CONVERT
Default: EVC_LT
Descriptions of system constant values and their numeric equivalents are listed in EmptyValueComparison Settings.
The Sort method returns ER_OK if it is successful, or a non-zero value if it is not.
